Among the many books of LN fantasy I read, this series clearly stands out - and one of the biggest reasons is that it's not actually a "LN fantasy", a very specific genre with many customs and rules, but much more of a traditional fantasy, with deep worldbuilding, always revealing bits of lore that might come to matter in a big way, or be just a background detail. In particular, I appreciate it having magic (if it could even be called that) that never loses its mystery and becomes purely practical, because it is just too otherworldly, a matter of gods and legends, not something for an adventurer to pick up from a book.
While it's not quite as good, it does somewhat resemble Apothecary Diaries in the way it sets up a world, drops in various noticeable characters, and lets it all play out instead of going straight for the story. Also, both are great stories that don't really resemble anything else coming out in LNs at the moment. And since I'm drawing comparisons, one could also say it distantly reminds me of Twelve Kingdoms, with both setting up weird and unearthly worlds, but populating them with characters that are all too human, and drawing a lot of interesting stories from the contrast between the too.
Reverie is not perfect; very noticeable is the tendency to give men and male-coded entities a lot more agency than women and female-coded entities, to bind women with more rules and give men more leeway even outside of those imposed by society, and to have women fall into a lot more distress - even if some of those have very satisfying resolutions.
Despite that, it was a very interesting trilogy that I'm sure will stay with me for a long time.
And finally, a personal aside: Riko is a relatively minor character but she's a damn hero in my book.
